Bookmarks won't let me create any new top level folders - I'm stuck with toolbarMenu and bookmarksMenu and I can't remove them. Somehow I created a bunch of tabs at the top of the content pane but I don't know how.What does the "open pages" window show?What does the "synch with table of contents" button do (it doesn't seem to work)?

"Sync with table of contents" is handy. When you click on a hyper text link, choose the "Sync with table of contents" menu item to have the closest table contents item selected (closest to page being viewed). This is happens immediately (it's not a mode which is turned on/off).

I've discovered that the "toolbar menu" in the bookmarks window lets you create a bunch of stuff that appears on a toolbar that you can see by going view -> toolbars -> bookmarks toolbar. The looked to me like tabs at the top of the content pane. Bookmarks menu in the bookmarks window lets you create stuff that appears when you click "bookmarks" in the main menu.

To see tabs for the pages in the "open pages" window you have go preferences -> options -> show tabs for individual pages - seems to default to off.

I don't understand your explanation about "synch with table of contents" menu item". What is a ""Sync with table of contents" menu item" ? Can you list the exact steps that show how "synch" works?

I knew you could add/delete boomarks. Didn't know about the show document tabs option.

The "Sync with table of contents" seems to work for me. After you click on a hypertext link, your place in the table of contents is no longer the table of contents item closest to the help page being displayed. The "Sync with table of contents" is supposed to select the table of contents item closest to the help page being displayed. That way, you can see the table of contents for that area of the help document.

I can sort of tell you maybe how to reproduce the synch problem. Make the bookmarks toolbar visible at the top of the window with 3 or 4 pages bookmarked. Make open tabs visible - also at the top of the window. Click on a hyper-link and select open in new page. Click the synch button - it works. Now click one of the tabs on the bookmark toolbar. Click the synch button - it doesn't work and the message on the status bar is "could not find the associated content item". Click on a hyper-link and select open in new page. Click the synch button - it works again.

This might not repro for you. There's a possibility that the problem is something to do with the fact that the tabs on my bookmarks toolbar are mostly pointing at "halfway down a page" instead of at the top of a page. I'd been testing to see that the bookmarks take you to the correct position on a page instead of always to the top of the page.

I can make the problem happen. The easiest way to make it happen is to go to the index and choose an API function like "insert_line". Maybe it's having to search to do the sync and limits how much searching it will do. Just a guess. The system is Qt program that we didn't write.
